Q50 InTouch works well with iOS 7.
Items to note are that I did not have to rediscovery the bluetooth setting, my device and the Q50 picked each other up.
Music worked exactly the same.
iTunes Radio was the new feature that worked well. The Q50 could not distinguish if the music was coming from the iPhone locally, via iMatch or from iTunes Radio. It displayed the track title, album title and single information.
Waiting for InTouch update from Infiniti to test the new features such as Pandora and iHeartradio apps on the Q50.
